haskellPackages.mkDerivation: use CC_FOR_BUILD if !stdenv.hasCC
Previously, we would try to calculate the name of buildPackages.stdenv.cc and then just hope that it is in PATH somehow. This definitely doesn't work in all cases. The new approach is to add buildPackages.stdenv.cc to depsBuildBuild which also populates CC_FOR_BUILD which we can directly re-use.
